Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain ingredients that cause drowsiness. Dextromethorphan is a commonly used cough medication and may interact with duloxetine. Ask your pharmacist about using those products safely.
Cimetidine is a nonprescription drug that is commonly used to treat extra stomach acid. Because it may cause undesirable interactions when used with duloxetine, ask your pharmacist about other products to treat stomach acid.
